feat(agent): optional agent-level workspace basePath override (#212)

* feat(agent): optional agent-level workspace basePath override

Add workspaceBasePath field to AgentEntity that optionally overrides
the workspace-level basePath. When set, the agent uses its own directory;
when null, it inherits the workspace's basePath (existing behavior).

- AgentEntity: new workspaceBasePath field with ALWAYS update strategy
- AgentGraphBuilder: agent-level override takes priority over workspace
- Flyway migration V121 for H2 and MySQL
- UI: form input in basic tab with i18n (zh-CN, en-US)

* fix(agent): rename migration V121→V125 to avoid Flyway conflict with upstream

Upstream already has V121__tool_disclosure_tier.sql. Rename our
migration to V125 (next available after V124).

* fix(agent): make MySQL V125 migration idempotent

Use INFORMATION_SCHEMA check before ADD COLUMN to avoid
"Duplicate column name" error on re-deploy.
